Jud's right, of course - thanks for the correction.

i added this comment line to those 3 sequences (well, it won't
be on the web site for an hour or so)

%e A020755 The first gap in A005117 occurs between 1 and 2 and has length 1. The next biggest gap occurs between 3 and 5 and has length 2. The next biggest gap is between 7 and 10 and has length 3. Etc. We are only interested in gaps that set new records.
